**Executive summary:** Autotune is a patent-pending algorithm that dynamically tunes polling step values for customer integrations to balance memory usage, step latency, and API rate limits—resulting in faster alert ingestion, fewer API requests, and lower resource consumption; production examples include halving API requests for a Microsoft Sentinel poller, cutting Defender for Cloud Apps requests by a third, reducing step latency by 15 minutes, and decreasing a Netskope poller's memory use by two thirds.
